Abstract
Polybrominated bisaryl compounds containing bromomethyl or bromomethylene groups are provided, as well as flameproof polymeric formulations comprising the compounds. The novel compounds exhibit a good thermal stability, and are particularly suitable for flame-retarding polystyrene thermoplastic foams. A process for making the polybrominated bisaryl compounds is also provided.
